I just ordered an Orange Pi Zero for a new NAS, but I'm curious about how the CPU is this new tiny thing compares to my old server. This small computer only has 512MB of RAM, so I'll only use it as a sshfs server for my current server to use as more storage. My current server has an AMD Athlon 64 3000+ @ 1.8Ghz, where this thing has a quad-core Allwinner H2+ @ 1.2Ghz. Which has more power?
